Abstract

Des engrenages de transmission connus en soi comprennent au moins deux roues d'engrenage en prise au moyen d'une cycloïde fermée de disque à came formée sur une roue et d'une couronne de galets sur l'autre roue dont les points de contact avec la cycloïde de disque à came décrivent des points sur une cycloïde raccourcie qui peut être mathématiquement exprimée par quatre paramètres z, r, e et q, avec l'angle de prise gamma entre la normale de la came et la direction de r. Une cycloïde de référence est associée à une roue et une courbe cycloïde qui se distingue de la courbe de cette cycloïde de référence par des écarts des paramètres q et r est associée à l'autre roue. Afin d'assurer une possibilité de détermination d'une prise optimale des parties de l'engrenage déjà au stade de la conception, la différence entre les modifications q et r donnent la valeur d'appariement c et le quotient de ces modifications donne le cosinus de l'angle maximal de prise gammamax, c étant déterminé en fonction de la qualité ISO requise et de la cote nominale 2r selon un tableau de normes correspondantes.
